• Charge transfer salts of tetrathiafulvalen (TTF) with five substituted <I>p</I>-benzoquinones (fluoranil, chloranil, bromanil, iodanil, and 2,3-dichloro-5,6-dicyano-<I>p</I>-benzoquinone) were prepared by diffusion and cooling methods. IR, Raman, and electronic spectra of these salts measured at room temperature showed that all except fluoranil salt formed two crystal phases, <I>i.e.</I>, the diffusion and the cooling methods gave a mixed-valent and a monovalent ionic phases respectively. The degrees of charge transfer (ρ) of the mixed-valent salts were estimated from the Raman frequencies of a<SUB>g</SUB> ν<SUB>3</SUB> of TTF, and nearly equal values (<I>ca.</I> 0.7) were obtained for all of them.
